Il più grande impianto fotovoltaico alpino della Svizzera, ubicato sulla diga del Muttsee, nel canton Glarona, produce elettricità dallo scorso autunno, ma solo oggi, giovedì, è stato completato. Ora l'impianto solare funziona a pieno regime, raggiungendo la sua massima capacità produttiva: i 5'000 moduli solari installati a 2'500 metri di quota possono produrre 3,3 gigawattora all'anno.
La centrale ha una superficie di 10'000 metri quadrati, pari a circa un campo da calcio e mezzo. In teoria potrebbe fornire elettricità a 750 famiglie. Per i primi 20 anni, tuttavia, la corrente è stata venduta al grande distributore Denner, che acquisterà questa energia tratta dal sole per i prossimi 20 anni.
